Warning!
G
In the event that the SRS malfunction indica-
tor lamp comes on during driving or does
not come on at all, the SRS may not be op-
erational. For your safety, we strongly rec-
ommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in inju-
ry.
Improper work on the restraint systems, in-
cluding incorrect installation and removal,
can lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact
your authorized Mercedes-Benz Center.
Warning!
G
Airbags are designed to reduce the potential
of injury and fatality in certain frontal
impacts (front airbags), or side impacts (side
impact airbags and head protection window
curtain airbags). However, no system avail-
able today can totally eliminate injuries and
fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma or other breathing trouble. To avoid this,
you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear your
seat belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and ensure that it is properly
positioned on your body.
Since the airbag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:

Sit properly belted in an upright position
with your back against the seat back-
rest.


58 Safety and SecurityOccupant safety

Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least ten
inches (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.


Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.


Occupants, especially children, should
never lean their heads in the area of the
door where the side airbag inflates. This
could result in serious injuries or death
should the airbag be triggered. Always
sit upright, properly use the seat belts
and appropriate size infant or child re-
straint system.


Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front airbag when it
is properly installed. Otherwise they will
be struck by the airbag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag.
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag which needs to deploy rapidly in a
side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door or rear


59 Safety and Security
Occupant safety
quarter trim panels where the side air-
bag inflates. This could result in serious
injuries or death should the side airbag
be activated.
(2) Always sit upright, properly use the seat
belts and use an appropriately sized in-
fant or child restraint system for all chil-
dren 12 years old or under.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have both rear side
airbags deactivated, then deactivation can
be accomplished upon your written request
to do so at your authorized Mercedes-Benz
Center at an additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
iAirbags are designed to activate only in
certain frontal impacts (front airbags)
and in side impacts (side impact and
head protection window curtain air-
bags) which exceed preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment tresholds, will they provide their
supplemental protection.
The driver and passengers should
always wear their seat belts. Otherwise
it is not possible for airbags to provide
their supplemental protection.
In cases of other frontal impacts,
angled impacts, roll-overs, other side
impacts, rear collisions, or other acci-
dents, the airbags will not be activated.
The driver and passengers will then be
protected by the fastened seat belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
ger that you replace deployed airbags
and repair any malfunctioning airbags
to ensure that the vehicle will continue
to provide supplement crash protec-
tion for occupants.

Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Center.


Airbags and emergency tensioning de-
vice (ETDs) are designed to function on
a one-time only basis. An airbag or ETD
that was activated must be replaced


No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger airbag cov-
er, door trim panels, or door frame
trims, and installation of additional elec-
trical/electronic equipment on or near
SRS components and wiring. Keep area
between airbags and occupants free
from objects (e.g. packages, purses,
umbrellas, etc.).


Do not pass belts over sharp edges.
They could tear.


Do not make any modification that could
change the effectiveness of the belts.


Do n o t h a ng i te ms su ch as c o at ha n ger s
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain airbag is deployed.


An airbag system component within the
steering wheel gets hot after the airbag
has inflated. Do not touch.


Improper work on the system, including
incorrect installation and removal, can
lead to possible injury through an unin-
tended activation of the SRS.


In addition, through improper work
there is a risk of rendering the SRS inop-
erative or causing unintended airbag de-
ployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact your authorized
Mercedes-Benz Center.


For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.


Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.

61 Safety and Security
Occupant safety
When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
Front airbags
Driver and passenger airbags are de-
ployed:

in the event of a frontal impact


if impact exceeds a preset deployment
threshold


independently of the side impact air-
bags
The airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The front passenger airbag will only be de-
ployed if:


the front passenger seat is occupied


the PASS. AIRBAG OFF indicator lamp
in the center console is not lit
(page 67)


the impact exceeds a preset deploy-
ment threshold.

2Passenger airbagSide impact airbags, window curtain
airbags
The side impact airbags and window cur-
tain airbags are deployed:


on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
The side impact airbags and window cur-
tain airbags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.!Do not place objects heavier than
20 lbs (9kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

62 Safety and SecurityOccupant safetyThe front passenger side impact airbag will
only deploy if the system senses that the
front passenger seat is occupied.
1Window curtain airbag
2Side impact airbagsSeat belts
When the engine is started, the seat belt
non-usage warning lamp< illuminates
to remind you and your passengers to fas-
ten your seat belts. If the driver’s seat belt
is not fastened before the engine is
started, the seat belt non-usage warning lamp< illuminates and a warning
chime sounds for approximately
six seconds when the engine is started.
The use of seat belts and infant and child
restraint systems is required by law in
most states and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
For more information on seat belts see
“Fastening the seat belt” (
page 41).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 65).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.

63 Safety and Security
Occupant safety
Warning!
G
Never ride in a moving vehicle with the seat
backrest reclined. Sitting in an excessively
reclined position can be dangerous. You
could slide under the seat belt in a collision.
If you slide under it, the belt would apply
force at the abdomen or neck. That could
cause serious or even fatal injuries. The seat
backrest and seat belt provide the best re-
straint when the wearer is in an upright po-
sition and the belt is properly positioned on
the body.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt.
Warning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been ap-
proved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
or to failure.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!

USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.


Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver airbag, pas-
senger front airbag, side impact airbags,
head protection window curtain airbags
for side windows), ETD (seat belt emer-
gency tensioning device), and front seat
knee bolsters. The system is designed
to enhance the protection offered to
properly belted occupants in certain
frontal (front airbags) and side (side im-
pact and window curtain airbags) im-
pacts which exceed preset deployment
thresholds.


64 Safety and SecurityOccupant safety
Emergency tensioning device (ETD)
The seat belts are equipped with emergen-
cy tensioning devices and belt force limit-
ers.
The ETD is designed to activate in the fol-
lowing cases when the seat belts are fas-
tened:

in frontal or rear-end impacts exceed-
ing a preset severity level


if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 56).
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants during a crash.


Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The
belt would also apply too much force to
the ribs or abdomen, which could se-
verely injure internal organs such as
your liver or spleen.


Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys, etc., as these
might cause injuries.


Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.


Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.


Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.


Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.


Never place your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat.
